IMPROVEMENT IN BURNERS FOR KEROSENE-LAMPS.

Specification forming part of Letters Patent No. 38,537, dated May 12,1863.

To 0. whom it may concern.-

Be it known that I, TIMOTHY RAYMOND, of Brooklyn, in the county of Kingsand State of New York, have invented a certain Improvement in Burnersfor KeroseneLamps; and I do hereby declare thefollowing is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and to theletters of reference marked thereon.

The nature of this invention consists in combining a spiral springattached to the flange or base-plate of the burner at one end with thelever or catch which secures the chimney in its place, substantially ashereinafter de scribed.

Figurel is a plan of the burner with the cone removed. Fig. 2 is a planof the cone. Fig. 3 is an elevation of the burner, partly in section.Fig. 4 is a vertical section showing the manner of attachment of thespring and its combination with the lever.

1 is the rim or flange or base plate of the burner. This is constructedin a manner similar in most respects to many in common use.

2 is the lever by which the chimney is secured in position.

3 is the spiral spring by which it is kept in place up against thechimney to secure the chimney in position. The lower end of the springis extended through the plate, turned under, and theiend further securedby soldering. At the upper end of the said spring one of the coils ishooked onto a hook formed at the inner end of the lever 2.

The form of the lever or catch, and its manner of insertion into theburner, is very much the that or nearly that described in Letters Patentgranted to me the 8th day of April, 1862.

Much diffi culty has been experienced in providing a simple, cheap, andreliable springcatch for kerosene burners. The ordinary flat spring hasbeen found unreliable and very apt to break, besides lacking thatelasticity necessary to secure the chimney with certainty in itsposition. The object of this improvementis to avoid that difficulty, andat the same time secure the advantages of the lever in securing thechimney to a lamp. The lever is probably the most convenientlymanipulated of any fastening in use, and for that reason is to bepreferred. This has been long in use, and so also has the spiral spring,combined with the sliding catch, but I am not aware that a spiral springhas been combined with the lever in the manner 1 have describedthat is,by attaching one end of said spiral spring to the base-plate and theother to the end of the lever. It is obvious, also, that besides theother advantages which this improvement possesses,itis much more easilyrepaired in case of derangement than the other kinds .of catches, as allthat is necessary to replace the spring is to loosen it from the bottomplate by melting off the solder, when it can be readily taken out andreplaced by a new spring.

Having thus fully described my invention, Iolaim- The combination of thelever 2 and the spiral spring 3 in the manner described, the parts beingconstructed, combined, and operating substantially as set forth.

TIMOTHY RAYMOND.
